REDwire Understanding cable flexibility

Bergen Cable Technology manufactures a wide variety of cable assemblies.

Cable construction plays a major role in wire rope flexibility. The more wires in a strand or cable of a given diameter, the more flexible it is. 

For example, if minimal flexing is required in an application, a 1x7 or a 1x19 strand, with seven and 19 wires respectively, is the best option. These strands are ideal for applications where the rope is a fixed member or a straight linkage. However, cables designed with 3x7, 7x7 and 7x19 construction offer increasing degrees of flexibility. These designs are used in applications where continuous flexing is a requirement.

A closer look at cable strands

Cable strands are available with various degrees of flexibility.

  • 1x7: This cable offers the least stretch and the stiffest construction. 
  • 1x19: This cable is fairly flexible, and resists compressive forces. The stronger cables are those more than 3/32 inches in diameter.
  • 7x7: This durable cable is ideal for general purpose construction because of its strength and flexibility. It can be used over pulleys.
  • 7x19: This is the strongest and most flexible cable with the greatest stretch. It is ideal for use over pulleys.
